To all whom it may concern."

Be it known that I, HENRY G. ELrBoRo, a citizen of the United States, residing at Chicago, in the county of Cook and State of .5 Illinois, have invented certain new and useful Improvements in Railway-Rails, of which the following is a specification.

The object of my invention is to provide an improved construction of railway rails i.o for the purpose of securing greater strength -and durability and at the same time to construct the rail oints in such a manner as to present a smoother tread surface to the wheels.

The objects of my invention and the means whereby they are accomplished will be fully apparent from the following specification and claims, taken in connection with the accompanying drawings, in which Figure 1 is a plan view of a railway rail constructed according to my invention, the tie-plates being omitted in order to more clearly show the joint. Fig. 2 is a cross sectional view of one form of my improved rail in connection with which there is shown a tie-plate adapted to hold the rail sections together and also a fish-plate and a fragment of a wheel. Fig. 3 is a detail perspective view of the outer part of the rail shown in Fig. 2. Fig. 4 is a detail perspective view of the inner part of the rail shown in Fig. 2. Fig. 5.is a cross sectional view of another embodiment of my invention. Fig. 6 is a perspective view of the form shown in Fig. 35 5. Fig. 7 is a cross sectional View of another embodiment of my invention. Fig. 8 is a perspective view of the form of my invention shown in Fig. 7. Fig. 9 is a cross sectional view of another modification. Fig.

so 10 is a perspective view of the form shown in Fig. 9.

In the form of my invention illustrated in Figs. 2, 3 and at the rail is made up of two longitudinal sections, an outer section 1 and an inner section 2 divided upon a plane passing substantially vertically through the central part of the head of the assembled rail. The outer part 1 of the rail may be constructed of Bessemer-steel, or of any carso bon steel as distinguished from special steel such as manganese-steel. The outer part is provided at its base with oppositely projecting flanges 3 and 4. The inner section 2 is constructed of manganese-steel or of some special steel offering a high resistance to wear. The inner section 2 is provided with a flange 5 projecting away from the web of the rail, and the web 6 of the inner section is of less depth than the web of the outer section so that in assembled position the fiange'5 of the inner section 2 rests upon the inner projecting flanged section 4 of the outer section 1. The inner faces of the webs 6 and 7 of the inner and outer sections are preferably recessed leaving a space 8 between the two sections, this form of construction being adopted for the purpose of reducing the amount of surface of the two rails which must be accurately finished. As shown in the drawings the two sections abut and are snugly fitted along the upper part of their inner surfaces, as indicated at 9 and along the lower part of their inner surfaces, as indicated at 10.

The assembled rail, as indicated in Fig. 2, rests upon a tieplate 11 provided with an upwardly projecting shoulder 12 against which the edge of the flange 3 abuts and with an upwardly and inwardly projecting lug 13, which embraces the edges of the flanges 4t and 5 and extends over the top surface of the flange 5. The tie-plate 11 being spiked to the ties, the rail sections 1 and 2 are held in fixed relation to each other and to the tie.

Fig. 1 is a diagrammatic illustration of the manner of assembling the rail sections to form a complete rail and this general manner of assemblage is followed in all the various forms of my invention. The joints 14 between the ends of the outer rail sections are staggered with reference to the joints 15 between the ends of the inner rail sections. The staggering of the joints forms an effectual safeguard against sagging of the rails near their ends and results in the production of a rail which is smooth ini tially and which remains level and smooth practically throughout its life. At no point is the rail weakened by a joint extending clear across. Where one longitudinal section of the rail is weakened by a joint the other section is continuous. By this means a practically continuous support for the wheels is ofiered at all points. 'The rail sections may be joined by the usual fish-plates 16, one fish-plate being sufficient for each joint by reason of the fact that one section of the rail is continuous at each joint in the other section.

As is well known the wear upon railway rails occurs almost exclusively upon the inner side of the head of the rail, that is, the side toward the center of the track. The greater wear at this point results from the fact that the weight of the rolling stock is principally supported at that point, and from the further fact that the wheel flanges rest against the inner part of the head of the rail especially on curves.

By constructing the inner rail section 2 of manganese-steel I secure at the point of greatest wear a rail possessing a high degree of resistance to the wearing tendency, while at the same time avoiding the expense of constructing the entire rail of that material. The outer section of the rail being subjected to less wearing action from the wheels of the rolling stock may be constructed of Bessemer-steel without sacrificing the ei'liciency secured by the use of manganesesteel for the inner section.

The form of my invention illustrated in Figs. 5 and 6 diflers from that illustrated in Figs. 2, 3 and 4 in that each of the rail sections 17 and 18 is provided with a flange projecting outwardly from the web, the webs of the two sections being of equal depth. One of the rail sections, 17, as illustrated in Fig. 5, is provided with a tongue 19, which fits into a correspondingly formed recess 20 along the base of the rail section 18. In this form the tie-plate 21 is provided with upwardly extending lugs 22 against which the outer edges of the base flanges 23 abut. In this form as in that previously illustrated, the inner faces of the webs of the rail sections 17, 18 are recessed leaving a space 24, the rail sections being accurately fitted together adjacent their upper and lower parts as illustrated.

In Figs. 7 and 8 I have illustrated another modification similar to that shown in Figs. 5 and 6, except that the rail section 25 is provided with a tongue 26 fitting into a groove 27 in the rail section 28, the tongue and groove being located upon the inside of the head of the rail above the space 24 instead of near the base of the rail as illustrated in Fig. 5.

In the form of my invention illustrated in Fig. 9 the tie-plate may be omitted. In this form the rail section 30 is provided with oppositely extending base flanges 31 and 32. Near its edge the flange 82 is provided with an upwardly extending shoulder 83. The rail section 84 in this modification is quite similar in cross section to the section 2 illustrated in Fig. 2, and at its lower edge is provided with a flange 35 which rests upon the upper surface of the flange 32 of the rail section 30. The edge of the flange 35 abuts against the upwardly projecting shoulder 33 on the flange 32 and is thereby held in proper relation to the other rail section.

In all of the various forms of my invention illustrated the inner rail section, thatis, the section toward the center of the track is designed to be constructed of manganesesteel or other steel of special hardness, while the outer section may be of Bessemersteel.

It will be obvious that the broad principle of my invention may be applied in other speciflc forms, those forms here illustrated and described serving to explain the principle of the invention and to exhibit the forms of its embodiment which I now prefer.
